.To aZZ whom it may concern:

Be it known that I, JOHN S. GRABILL, of

Hayesville, in the county of Ashland and State a sectional elevation of a part of the tubular shaft enlarged, and showing the end of the triplever and the trip-cord connect-ion.

The object of this invention is to provide horse-powers simple in construction, inexpensive in manufacture, and strong and durable in use.

The invention consists in the construction and combination of various parts ofthe horsepower, as will be hereinafter fully described.

A represents a vertical shaft, which is made of gaspipe one and a half inch in diainet-er,or othersuitable size. The lower end ofthe shaft A revolves in a socket-bcaring, B, attached to the floor or baseframc or other suitable support.

Upon the shaft A, near its upper end, is placed a loose wheel, which is formed of radial spokes O, bolted at their inner ends to and between two metallic plates, 1), which are perforated centrally to receive the shaft A,and are flanged around the said perforations to form hearings to rest upon the said shaft. Vith the upper and lower edges of the outer ends of the spokes O are connected annular plates E, to form a groove to keep the hoisting-rope F, attached to and wound around the wheel, from slipping off.

The flange of the lower hubplate, D, rests upon the upper side of the inner end of the radial arm (3-, which is formed of two bars rigidly secured at their inner ends to the shaft A, and kept at the proper distance apart by blocks interposed between and secured to them,as indicated by the dotted lines in Fig.2.

The arm G- is made a little longer than the diameter of the wheel 0 D E, and to its inner end is rigidly attached the inner end of the sweep H, which is inclined downward and outward to bring its outer end into proper position to receive the draft.

The sweep II is made of two bars, and is secured to the brace I at its point of intersection with the said brace. The brace I is also made of two bars secured at the upper end to the outer part of the radial arm Gr.

The brace I inclines downward and inward, and its lower end is attached to thelowerpart of the shaft A.

The shaft A, radial arm G, inclined sweep H,and inclined braceI form a firm and strong rotary frame to receive the draft and give motion to the loose wheel 0 D E. The shaft A is held in a vertical position by two bars, J, the inner ends of which are perforated to receive the upper end of the said shaft A. The outer ends of the bars J are attached to the frame of the building in which the power is set up, or to posts set in the ground,when the power is to be used out-of-doors.

The bars J are free to turn around the upper end of the shaft A, so that they can be arranged at any desired angle with each other, as the construction of the frame of the buildingor the position of the posts may require.

K is a lever, which passes through the space between the parts of the brace I and sweep H, and is pivoted to the said brace, withits inner end projecting into the interior ofthe shaft A through a slot in the side of the said shaft, as shown in Figs. 2 and 3.

To the outer end of the lever K is pivoted the lower end of a clutch-bar, L, which passes up through the space between the parts of the radial arm G, and is made of such a length that when raised its upper end will enter a space between the spokes G ofthe loose wheel, and thus cause the said wheel to be carried around by and wit-h the shaft A in its revolution.

To the inner end of thelever K is connected by a swiveled connect-ion, M, the end of the trip-cord N, which passes up through the interior of the upper part of the shaftA, passes around a guide-pulley, O, the block of which is swiveled to an arm, '1 attached to 'the bar J or other suitable support, and passes thence to some place where it can be conveniently reached and operated.

Directly beneath the lever K is placed the lower arm of a right-angled lever, Q, which passes through the spaces between the parts of the sweep H and brace I. The lever Q is pivoted at its angle to the sweep H, and to the end of its upper arm is hinged the lower end of the lever B, which passes up through the space between the parts of the radial arm G, and is pivoted to the said arm. The lever B has a short slot formed in it to receive the pivoting-bolt to give the said lever the necessary freedom of movement. The upper end of the lever B projects so far above the radial arm G that when the said upper end is swung inward it will come in contact with the lower annular plate, E, of theloose wheel, and serve as a brake to check the movement of the said loose wheel when the clutclrbar L is withdrawn therefrom. The inner end ofthe lower arm of the lever Q does not extend quite to the shaft A, and passes through a slot in the hanger S, the upper end of which is attached to the lever K at a little distance from the shaft A, and which is made sufficiently heavy to draw down the inner end of the lever K when left free, and raise the clutcl1-bar L into gear with the loose wheel 0 D E. To the lower end of the hanger S is pivoted the end of the lever T, which is pivoted to the shaft A, and the other end of which projects into such a position that it can be readily reached and operated by the driver to withdraw the clutch-bar L from the wheel 0 D E and apply the brake-lever It to the said wheel when it may be necessary or desirable to employ a driver.

\Vith this construction, when the horsepower is used for operating a hay-carrier, the hay-fork is loaded and the cord N is released, which allows the weight of the long arm of the lever K and of the hanger S to raise the clutch-bar L between the spokes O of the hoisting-wheel, so that the said wheel will be revolved and the hoisting-rope F wound upon it, raising the loaded hay-fork and drawing the hay-carrier to the place of unloading. Then the fork is tripped in the ordinary manner to discharge the hay, and the cord N is drawn upon to operate the lever K and with draw the clutch-barLfrom the hoisting-wheel O D E, allowing the hay-carrier to run back to the place of loading and the hay'fork to descend, to be again loaded. As or before the hay carrier and fork reach the place of loading, the cord N is further drawn upon to apply the brake-lever R to the annular plate or flange E of the hoisting'-wheel, to check the backward movement of the said hoistin g-wheel and prevent it from being turned back so far as to allow the hoisting-rope F to slaeken and sag.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the vertical shaft A, the radial arm G, and the inclined sweep II and brace I, attached to the said shaft and arm, the loose hoisting-wheel G D E, and the clutch-bar L and its lever K, of the hanger S, the cord N, and its swiveled connection M, substantially as herein shown and described, whereby the said hoisting-wheel can be thrown into and out of gear from a point at a distance from the power, as set forth.

2. In a horse-power, the combination, with the radial arm G, the inclined sweep H, and the vertical shaft A, of the inclined brace I, substantially as herein shown and described, whereby the said shaft, arm, and sweep are strengthened against the draft-strain, as set forth. 4

3. In a horse-power, the combination, with the radial arm G, the inclined sweep H and brace I, the clutch-lever L K and its slotted hanger S, the tripcord N, and the loose hoisting-wheel O D E, of the right-angled lever Q and the lever It, hinged to the said lever Q and pivoted to the said radial arm G, substantially as herein shown and described, whereby the said brake-lever can be applied to the said loose wheel by operating the said clutch-levcr, as set forth.

4. In a horsepower, the combination, with a shaft and a hoisting-wheel thereon, of the clutch-lever LK, provided with the hanger S, the brakelever Q It, engaging the said hanger, and the lever T, pivoted to the said shaft and hanger, substantially as herein shown and described.

JOHN S. GR-ABILL.
